Question 1031934
{{{(x+5)/((x-4)(x+8))}}}


Critical x values are -8, -5, 4.
These cut the x-axis number line into four intervals, being expressed in interval notation:   (-infin, -8), (-8, -5], [-5, 4), (4, infinity).


x=5 is a zero of f.
x=4 and x=-8 are vertical asymptotes.


Test for signs of f in each interval.  Tell if you need help knowing how to do that.
